Overall I think its a game that will be successful and rightfully so. Art is good. I expect cinematics to be fine as well once they get to the polishing stage - and origin characters replace the custom character in cinematics. Other kinks will probably fixed along the way, at least I don't see anyhting major that could affect the game's mass market success. It's a game that will resonate with the DOS crowd I guess even though there are D&D mechanics in there.
Now for me personally the game is a disappointment after the first couple of hours of hype. D&D is in there, but there is a lot of Larianism at the core of the game design that broke completely the action economy of 5e. Yeah, it might work for those who don't care for D&D 5e, but to me its absolutely no improvement, I have the same feeling I had playing DOS2 and I loathed combat there.
Map and origin characters are another 2 points coming from DOS2 and I don't like either of them and the influence they have.
Encounter design - as a result from how they make maps and combat - I'm not impressed, I really think its poorly designed and heavily encourages metagaming.
Story and companions so far have not connected with me, but it might be a matter of time and just companions available.
Overall it has a tremendously gamey feeling, not at all reminding me of BG-styled games, but a lot more of DOS2. The game never fails to remind me its a game and you can exploit it - because actually they want you to as they have added so many things that you can exploit to be 'creative' with the result that you always are better off using Larian's ideas than sticking to D&D 5e options.
But this is personal taste. As I said before, I think this will be a critically acclaimed and well selling game. I doubt though that for the majority of BG-fans its what they are looking for and I don't think people who want a good D&D 5e experience in their game will be satisfied either. Might be Larian makes more concessions to them, but so far reducing fire seems the biggest one after messing up the balance completely.
